3 Claims.

This invention relates to new and useful improvements in a means forcoiling chenille strips.

The invention has for an object to characterize said means by a cover ortube and by a wire lining mounted therein, with the coils thereofclosely wound, or substantially closely wound. It is proposed that thechenille strips or other cord or threads desired to be treated accordingwith a process for using the tube, be engaged through the tube andmanipulated as hereinafter more fully explained.

Heretofore tubes for the treatment of chenille strips have been knownbut these tubes have been formed with threads cut on their inner wall toassist in forming the outside of the chenille strips, or other cords,engaged in these tubes. While such threads have worked with somesatisfaction I have discovered that far superior results may be obtainedby the use of a wire in helical form lining the inside of the tube. Ihave found that the threads are objectionable because of theirshallowness and roughness. While on the other hand, the use of a wirewithin the tube has proven to be very satisfactory. With the wire,chenille strips have been formed to present -a uniform and smoothappearance, far superior to other methods heretofore used.

Still further the invention proposes an arrangement whereby the wirewithin the tube may be stretched or released so as to change the pitchof its coils to adapt the tube to produce treated strips and cords withdifferent degrees of surface formation. Still further the inventionproposes the construction of a tube as mentioned which is simple anddurable and which may be manufactured and sold at a reasonable cost.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawing, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. l is a plan view of an apparatus with tubes constructed inaccordance with this invention, to be used for surfacing chenillestrips, cords, and the like.

Fig. 3 is a fragmentary longitudinal sectional view of a tubeconstructed in accordance with this invention.

Fig. 4 is a side elevational view of a chenille strip treated inaccordance with this invention.

(Cl. zzz- 62) y Fig. 5 is a longitudinal sectional view of another wirelined tube constructed in accord-ance with a modification of thisinvention.

It is advisable to best understand the invention 5 to first understandthe process for treating the chenille strips, yarns, and cords. Theapparatus embodying the process, in accordance with this invention,includes a container IIl having opposed side walls III*EL through w ch aplurality of covers or tubes II are mounted. These tubes are so arrangedthat their end portions project from the side walls. A gas heater tube,or other type of heater, is mounted across the bottom area of thecontainer II). As illustrated a heater I2 comprises a gas pipe having aplurality of openings 15 I3 through which the gas may come out and burn.This pipe I2 is supplied with gas from a flexible tube I4. The containerIll may be provided `with a removable cover I5 so as to assist inholding the heat produced by the burner within the container. This heatis utilized to heat the intermediate portions of the tubes I I.

The container I0 is supported at its ends by vertical links I6. PintlesI1 connect the links I6 with the ends of the container Ill. These links25 are pivotally supported at their botto-m ends by pintles I8 ooactingwith brackets I9 mounted on a table or bench 2D. The container Ill isalso supported at its ends by connecting rods 2I. These connecting rodsare connected with the 30 ends of the container by pintles 22. Theconnecting rods l2I engage over cams 23 which are mounted on a shaft 24.The shaft 24 is rotatively supported in bearings 25 mounted on the table20. A pulley 26 is mounted on one end of the shaft 35 24 for engagementby a driving belt not shown in the drawing. The arrangement is such thatwhen the shaft 24 rotates, the container I0 will be oscillated in ahorizontal plane forwards and rearwards.

A pair of feed rollers 21 `are supported upon brackets 28 mounted on thetable 2D and engage a plurality of chenille strips, or other cords, 29for drawing the same from a supply. These strips, cords, or yarns engagethrough the tubes Il and 45 at their other ends engage between a pair ofrollers 30 mounted on bearings 3| supported on the table 20. Theserollers 30 assist in drawing the strips, or yarns 29 through the tubes II. The rollers 21, and 30 are driven by a suitable driving 50 device,including pulleys 32, and 33 engaged by a belt 34. A driver wheel 35 isassociated with one of the pulleys 32 and is adapted to rbe engaged by adriver belt not shown on the drawing.

The constructions of the tubes II form the 55 basis of this invention.Each tube ll comprises a tube lla, preferably circular in transverse andcross section. This tube is lined with a wire 36 wound in helical form.The wire 36 necessarily is in the form of a spring, preferably its turnsshould be closely wound, or nearly closely wound. This spring 36 may benormally of a slightly larger diameter than the inside` diameter of thetube I la so that; when it is engaged into the tube it frictionallymaintains its position. The chenille strips 29, or cords, are engagedthrough the coils .of the spring 35. In Fig. 4a piece of the chenillestrip 29 has been illustrated, so that the character thereof may beobserved and better understood.

The operation of the device is as follows:

The chenille strips 29 are threaded through the tubes Il. The heater l2is turned on so as to heat the tubes and then the shaft 24 is setrotating to cause the connecting rods 2| to rapidly oscillate thecontainer IG, and consequently the tubes Il longitudinally. The strips29 are slowly drawn through the tubes, during the oscillating thereof.The springs 36 or coiled wire, will rub, twist and form the surface bresof the strips 29, bending and arranging them to be uniformally placed.Because of the smoothness and evenness of the wire 35 it will be foundthat the chenille strips when coming out from the tubes will beexceptionally smooth and uniform.

In Fig. 5, a modied form o-f the invention has been disclosed whichdistinguishes from the prior form especially in the fact that anarrangement has been provided by which the pitch of the wire within thetube l I may be varied. According to this form of the invention thetubes l I include a. circular tube Ilaa in which a coiled wire 36 isdisposed. This wire has its ends fixedly connected with collars 40.These collars have inturned flanges engaging complementary anges onadjacent collars 4l, s'o that these collars are rotatively connected.The collars 4I are fixedly connected with bushings 42 which threadedlyengage end portions of the tube Ilaa and which extend from the ends ofthe tubes. The extended end of the bushings 42 are provided with flanges43 by which they may be manually gripped and turned.

When the flanges 43 are turned, the bushing 42 may be threadedly movedinwards or outwards of the tube I Iaa. This will stretch or allow thespring 36 to contract. Thus the pitch of the turns of the spring 35 maybe varied.

When this tube is used it will be found that it is possible to controlthe extent of the surfacing produced by the tube, by varying the pitchof the wire coil 36. When the turns are separated further apart thatwill produce a different effect upon the strip than if they were closertogether.

Each of the bushings 42 are also lined with coiled wires or springs 36".However these wires or springs are stationary. They serve to assist insurfacing the strips, cords, and threads passed through the tubes. Thetubes Il are to be used in an apparatus as illustrated and describedrelative to Figs. 1 and 2.

In other respects this form of the invention is identical to the priorform and its application will be readily understood.

While I have illustrated and described the preferred embodiments of myinvention, it is to be understood that I do not limit myself to theprecise constructions herein disclosed and the right is reserved to allchanges and modications corning within the scope of the invention asdened in the appended claims.

Having thus described my invention, what I claim as new, and desire tosecure by United States Letters Patent is:

1. A wire lined member for surfacing chenille strips, yarns, and cords,comprising a cover, a wire in helical form lining the inside wall ofsaid cover, and means for stretching said wire for changing the pitch ofits helical form.
